Antlion ModMic Wireless Battery Swap

I’ve used an Antlion ModMic Wireless since I started my first job (where I regularly took calls 6+ hours a day). Over time, its runtime has dropped from a full day to about half, and Antlion doesn’t sell replacement batteries, so officially my only fix was a new mic. But it’s held together with just three screws, so swapping the battery is easy enough (took me 15 minutes).

The base of the mic is a two-part plastic body held together by three small screws, with nothing glued.

The cell is a 502030 LiPo cell (3.7V, 250mAh, dated 2022.04.22), stuck with double-sided tape and soldered to two pads. That “502030” is the cell’s size (5 x 20 x 30mm), which is all you need to find a replacement. I ordered a replacement 502030 from Amazon ($8 after tax). Unfortunately there’s no space to choose a larger size.

Mine came with a JST plug, so I snipped it off (don’t cut the wires at the same time!). The old cell comes off by desoldering its two leads and working a piece of cardstock underneath to release the double-sided tape without damaging the old cell. The replacement goes in the same way - leads soldered to the same pads, and taped down in the same spot. Screw it together the same way it came apart.
